IMPROVEMENT IN unav-BOATS.

Specification forming part of Letters Patent No. 116,024, dated .lune20, 1871.

l To all lwhom it may concern:

Be it known that I, HENRY CLENNY, of' Gallatin, in the county of Sumnerand State of Tennessee, ha ve invented certain Improvements in Boats forTransporting Freight, Passengers, Sto., of which the following is aspecifistructed on my plan, and Fig.' 2 is a side elevation of the same.

In the drawing, A represents the hull or body of my boat, which, in its'general form, resembles an ordinary hat-boat or scow; it being of arectangular form, with straight sides. Instead, however, of the usualflat bottom, with two inclined ends, I divide the under side of my boattransversely into four faces, a, b,

' c, and d, which shouldv be of about the fonowing` proportions: The oneat the bow eight feet in length, with an inclination of about fifteendegrees 5' the second, seventeen feet in length and horizontal 5 thethird, eighteen feet in length, with aninclination upward toward thestern of from two to four degrees; and the last seven feet in length,with an inclination of about twelve or thirteen degrees. These faces areinclined fore and af't only, and are allhorizontal in their transversesection. The boat thus constructed I have found in practice to be easilypropelled and steered, both when light and when loaded.

In loading the boatthe weight. should be placed principally on theforward portion,

above the rear part'of face b, as it depressesl `the forward end mainlyand givesto the boat 4 the best poise orposition in the water. 0n

the boat thus constructed I place an overhanging deck of the form shown,and on the rear part of this deck I mount a'vertioal shaft, C, andprovide it with a sweep, D, and a large lbevel cog-wheel, E. In rear ofthe shaft C I mount a horizontal shaft, F, and secure thereon a largewheel, G, and a bevel-pinion,H, the latter arranged to gear into wheelE, as shown.

lower the other.'

`On-the deck I mount a long horizontal shaft, I, with its rear endextending out over the stern, and to the forward end of this shaft Isecure a pinion, J, gearing into wheel G, and to the rear end of theshaft secure a bevel -pinion, K. To the stern I secure projecting armsd,and in these arms mount a horizontal transverse shaft, L, providedwith two loose bevel- I pinions, Maa-nd N, which gear into oppositesides of pinion K, so that the pinion Will turn them in oppositedirections. To the outer end of sha-ft L I attach a paddle-wheel, O,which is thus brought behind one of the rear corners or quartersot' theboat. 0n the shaft L, between the wheels M and N, I place a' slidingclutch, P, which is prevented from turning by a spline, t', on theshaft, and which may be engaged with eitherv the wheel M or N, accordingas it is desired to have the shaft and thel paddle-wheel turn forward orbackward. A hand-lever, R, mounted in a suitable support, is connectedwith clutch P for convenience in shifting the same. The sweep, beingdrawn around by means of a horse attached thereto,

sets the gearing in motion and turns the paddle-wheel, 'which propelsthe boat forward or backward,accordingto whichof the two wheels theclutch is engaged with. To provide for steering and directing the boatin its course I pivot to the stern, on the opposite side to the wheel, alarge oar or sweep, S, as shown.

I have found in practice that a boat fifty feet in length, constructedon my plan, may, when loaded, be propelled with ease and at aconsiderablev speed, by a single horse` and that it may be, readilysteered and handled by a' single man.V 1

My boat being possessed of theabove qualities, and being, moreover,constructed at a small expense, will be found of great-service in manyplaces as a ferry-boat or a transport for freight. ferry purposes Iprovide it with suitable railings, and also with two platforms, T,hinged to the sides opposite each other, and connected by a rope passingaround a windlass, U. The windlass, being turned, raises one of theplatforms, and at the same time lowers the other; or, by fastening upeither of the platforms, the windlass may be used lto raise or Whenarrangedin this man-g PATENT QFFICE.

When the boat is to be used for 11er one man can readily handle theplatforms of the boa-t, and connected by a rope or. chain when landingor starting the boat. to a windlass, U, substantially as described,Having thus described my invention, what whereby one is raised as theother is lowered. I claim is- HENRY GLENNY.
